Simple Planes Fixes

Simple Planes Fixes is an unofficial bug-fix and compatibility addon for Simple Planes 3.0.1.7 on Minecraft 1.12.2.

The original 1.12.2 version of Simple Planes contains several broken crafting recipes and optional-mod integrations caused by incorrect item IDs, missing metadata, and compatibility content being registered even when the required mod or materials are unavailable.

This addon repairs those issues while leaving the original Simple Planes jar untouched.

What does it fix?

Biomes O' Plenty compatibility

Several Simple Planes recipes for Biomes O' Plenty use item names or metadata that do not match the actual Biomes O' Plenty 1.12.2 items.

Simple Planes Fixes restores the intended recipes for supported Biomes O' Plenty wood types, including:

• Planes
• Large Planes
• Cargo Planes
• Helicopters

It also fixes the missing metadata that prevented Biomes O' Plenty helicopter recipes from loading correctly.

Unsupported aircraft, such as Dead Wood variants, are hidden when the required materials do not actually exist.

Junk Engine recipe

The original Junk Engine recipe references vanilla coal without the metadata required by Forge 1.12.2.

Simple Planes Fixes supplies a corrected recipe so the Junk Engine can be crafted normally.

Optional integration cleanup

Simple Planes registers aircraft for several optional integrations even when their required materials are unavailable. This can leave unusable aircraft visible in JEI and the creative inventory.

Simple Planes Fixes conditionally hides these aircraft when their required materials are unavailable, including:

• Fruit Trees aircraft
• Oh The Biomes You'll Go aircraft
• Unsupported Biomes O' Plenty aircraft
• Crimson and Warped aircraft when compatible backported materials are unavailable

The aircraft items themselves are not unregistered, helping preserve registry and save compatibility.

Crimson and Warped compatibility

The Minecraft 1.12.2 version of Simple Planes contains Crimson and Warped aircraft even though those wood types did not exist in vanilla Minecraft 1.12.2.

Simple Planes Fixes includes conditional compatibility for Future MC. Crimson and Warped recipes are enabled only when the necessary Future MC materials are actually registered.

If the required materials are unavailable, the aircraft are hidden instead of appearing as unusable items.

Requirements

Required

• Minecraft 1.12.2
• Forge
• Simple Planes 3.0.1.7

Optional integrations

• Biomes O' Plenty
• Future MC
• Just Enough Items (JEI)

JEI is not required. When installed, Simple Planes Fixes removes unavailable integration aircraft from the JEI item list.

Client & Server

Simple Planes Fixes should be installed on both the client and server.

Installation

1. Install Simple Planes 3.0.1.7.
2. Place Simple Planes Fixes in the same mods folder.
3. Launch Minecraft normally.

Do not remove or modify the original Simple Planes jar. This project is an addon and requires the original mod.

Scope

The goal of Simple Planes Fixes is to restore functionality clearly intended by the original Minecraft 1.12.2 release.

It does not invent substitute recipes for integrations that are absent or incomplete. If an optional mod or required material is unavailable, its corresponding aircraft are hidden instead of being given unrelated crafting recipes.
